CuSO4 (s) vs CuSO4 (aq) Copper sulfate is also known as cupric sulfate. Copper sulfate is a salt of copper +2 ion and sulfate anion. When a copper +2 solution and a sulfate solution (potassium sulfate) are mixed together, a copper sulfate solution will result. Copper sulfate has several types of compounds, which differ […]

CuSO 4 ranges in color from grayish white in powder form to bright blue in crystal form. Because of the crystal color, CuSO 4 is sometimes called bluestone.. CuSO 4, or copper sulfate, is a salt that is commonly used in pesticides, herbicides, algicides and fungicides.It is safe when handled properly but can be poisonous if ingested orally, according to the National Pesticide Information Center.

Copper gluconate and copper sulfate were reported to be used as nutrients in milk products, processed fruit juices and drinks, soft candy, snack foods, beverages, chewing gum, and baby and infant formula. In addition, copper sulfate was reported to be used as a processing aid in alcoholic beverages. 49 FR 4009 (2/1/84)

Here's a much more direct method: just add a stoichiometric amount of calcium chloride to a concentrated aqueous solution of copper sulfate: $$\ce{CuSO4(aq) + CaCl2(aq) -> CaSO4(s) + CuCl2(aq)}$$ If the copper sulfate you have is in the anhydrous form (white powder), then add 695.3 mg of pure $\ce{CaCl2}$ per 1000 mg of pure $\ce{CuSO4}$.

Zn(s) + CuSO4(aq) --> Cu(s) + ZnSO4(aq) Using our ending solution from the last reaction, we carefully weighed out about 2 grams of mossy zinc to add! The result of adding the zinc caused fizzing, color change of the zinc (black-red) and resulted in copper formation!

Chemical Transformations of Copper Introduction: Copper was one of the first metals to be isolated, due to the ease of separating it from its ores. It is believed that the process was known (metallurgy) as early as 4500 BC. It is a ductile, malleable metal and is easily pounded and/or drawn into various shapes for use as wire,

The Copper Lab demonstrates stoichiometry in chemistry. Stoichiometry is helpful in calculating the amount of an element or compound in chemical reactions. For the lab, stoichiometry was used to predict the amount of copper that would be left over.
